Flue Damper Kit Instructions
INSTRUCTIONS
If you are installing an electrically operated flue damper
onto a boiler that also requires boiler pump control then
you cannot choose an on/off controlled boiler pump.
Instead, you MUST choose a modulation controlled
boiler pump, where the modulation signal is provided by
the boiler but the power supply is provided externally to
the boiler, but MUST be on the same phase supply.
This is done at the Boiler Pump page shown by
selecting the “Modulation from Boiler” option.
If you are installing an electrically operated flue damper
onto a boiler that does not require boiler pump control
then you can select No Boiler Pump.
This is done at the Boiler Pump page shown by
selecting the “No Boiler Pump” option.
For either of the selections above you can now
configure the Flue Damper.
This is done at the Cascade Flue with Electronic
Damper Control page shown by selecting the “Yes”
option.
The user can now proceed with the configuration
of the boiler following the remainder of the
commissioning process.
